Abstract

This invention relates to one of microorganisms which is a mutant of Microbacterium named 851R. The main characteristics of this strain are as follows : a Gram-positive bacterium, motionless, with nitrate reduction ability, able to produce H2S, alive in milk heated to 63°C for 30 minutes or to 72°C for 15 minutes. The thallus is of red or orange red colour. However, the colour of the thallus is turned to pink at about 38°C
and to colourless at 40°C. In particular, the DNA of the strain contains R fragment which is detectable with a special R fragment DNA probe.
The invention also relates to an industrial process for producing single cell protein nutrient solution by an application of the bacterium. In this process, a Microbacterium strain 851R being cultivated in this invention is the producing strain, a soybean medium or starch medium acts mainly as the producing medium.
